I have installed OpenShift3 with Docker and Kubernetes with the ansible installer. After the installation I want to create my docker registration on my master but I get the following error (I read it was something with SSL but I can't find a solution): commands (from the sample):
[root@ip-10-0-0-x centos]# export CURL_CA_BUNDLE=`pwd`/openshift.local.config/master/ca.crt
[root@ip-10-0-0-x centos]# sudo chmod a+rwX openshift.local.config/master/admin.kubeconfig
[root@ip-10-0-0-x centos]# sudo chmod +r openshift.local.config/master/openshift-registry.kubeconfig
[root@ip-10-0-0-x centos]# oadm registry --create --credentials=openshift.local.config/master/openshift-registry.kubeconfig --config=openshift.local.config/master/admin.kubeconfigerror:

Your local kubeconfig file (that oadm is using to connect to the server) should have been generated by the Ansible installer - can you verify that is the case? The file is in ~/.kube/config - does it point to the system that the Ansible installer used? Are you using an IaaS for OpenShift, deploying to local machines, or Vagrant?
